Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, the utility model is a simple steel mesh lifting device. Background Art

[0002] In modern construction projects, the installation and fixing of beam and slab reinforcements are indispensable key links. In this process, the placement of protective layer pads and horse stool bars is particularly important. However, traditional operation methods are often inefficient, labor-intensive, and require extremely high operating skills and physical strength of workers. At present, when carrying out these tasks, workers need to place them one by one, which undoubtedly increases their labor intensity. The protective layer pads are mainly used to form a layer of isolation between the steel bars and the formwork to prevent the steel bars from being more easily corroded due to insufficient thickness of the protective layer, thereby affecting the strength and durability of the components. The horse stool bar is a temporary support used to support the upper steel mesh before concrete pouring to ensure its stability and position accuracy during the pouring process. When placing the protective layer pads, workers need to lift the bottom steel bars or steel mesh so that pads can be placed between the steel bars and the formwork. However, due to the large number of pads and the need to ensure that each pad is placed in place, this undoubtedly increases the workload of workers. Similarly, when placing the horse stool bar, workers also need to lift the upper steel bars or steel mesh to ensure that the horse stool bar can stably support the upper steel mesh. However, in actual construction, since the placement of protective layer pads and horse stool bars needs to be carried out one by one, workers often fail to place them properly due to physical exhaustion after working for a long time. This not only affects the construction effect, but may also lead to rework, thereby increasing project costs and time. Therefore, how to reduce the labor intensity of workers and improve the efficiency and quality of placing protective layer pads or horse stool bars has become an urgent problem to be solved.

[0004] In order to achieve the above-mentioned technical objectives, the utility model discloses a simple steel mesh lifting device, including a force applying rod, a hooking rod and a support rod are provided at the lower end of the force applying rod, the hooking rod and the support rod are both located on the same side of the force applying rod, and the hooking rod and the support rod form an inverted F-shaped structure with the force applying rod, and the support rod is located above the hooking rod.

[0015] Figure 2 It is a front view structural schematic diagram of a simple steel mesh lifting device of the utility model. DETAILED DESCRIPTION

[0016] The following is a detailed explanation and description of a simple steel mesh lifting device of the utility model in conjunction with the drawings in the specification.

[0017] like Figure 1-2 As shown, the utility model discloses a simple steel mesh lifting device, including a force applying rod 1, and a hooking rod 2 and a support rod 3 are arranged at the lower end of the force applying rod 1. Specifically, the hooking rod 2 and the support rod 3 are both located on the same side of the force applying rod 1, forming a unique inverted F-shaped structure. This arrangement not only makes the device structure more stable, but also greatly enhances the flexibility and convenience of operation. The support rod 3 is placed above the hooking rod 2, so that workers can more easily control the lifting height of the upper steel bars or steel mesh during operation, thereby facilitating the placement of the horse stool reinforcement.

[0018] In actual application, when placing the protective layer pad, the worker only needs to hold the device with one hand, pass the hook rod 2 through the bottom steel bar (mesh) placed on the template, and then press the force rod 1 downward to easily pry up the bottom steel bar (mesh). At this time, the other hand can accurately place the protective layer pad to the predetermined position. When placing the horse stool reinforcement, the worker only needs to hold the device with one hand, pass the support rod 3 under the upper steel bar (mesh), and then pull the force rod 1 upward to easily lift the upper steel bar (mesh). At this time, the other hand can accurately place the horse stool reinforcement to the predetermined position. This two-handed collaborative operation method not only makes the entire construction process smoother and more convenient, but also greatly improves work efficiency. In addition, due to the easy operation of the device, workers do not need too much physical strength and skills, thereby greatly reducing labor intensity. In addition to the above advantages, the device also has the characteristics of simple structure, easy preparation, easy to carry and use. This makes the device more widely used in construction sites and can meet the needs of different scenarios. At the same time, due to the low production cost of the device, it also has a high cost performance and is suitable for use in a large number of construction sites.

[0019] In one embodiment of the utility model, the length of the hooking rod 2 is the same as that of the supporting rod 3, which ensures the stability of the structure. One end of the hooking rod 2 is a connecting end, which is smoothly connected to the force-applying rod 1 through an arc-shaped connecting rod 4. This connection method not only ensures the firmness of the structure, but also makes the device more flexible during use. The connecting rod 4 serves as a fulcrum, which can easily pry up the steel bar (net), greatly reducing the labor intensity of the workers. The other end of the hooking rod 2 is a free end, which is provided with a beveled surface 21, so that the hooking rod 2 is smoother when passing through the steel bar (net). The angle between the beveled surface 21 and the axis of the hooking rod 2 is set to 30°, which can ensure that the hooking rod 2 can smoothly pass through the steel bar (net). In actual use, workers only need to pry lightly to easily lift the steel bar (net), which greatly improves work efficiency. The force-applying rod 1 is the main force-bearing component for prying, and a holding rod 5 is vertically connected to its upper end. The setting of the gripping rod 5 fully considers the ergonomic principles, and its shape and size meet the requirements of comfort and stability of human hand grip. Through the gripping rod 5, workers can accurately find the force application point, making the prying process more labor-saving. At the same time, the gripping rod 5, the hooking rod 2 and the support rod 3 are all located on the same side of the force application rod 1. This layout makes it easier for workers to use and more convenient to operate. In order to improve the gripping feeling, the gripping rod 5 is also provided with an anti-slip sleeve 6. The anti-slip sleeve 6 is made of a material with a high friction coefficient, which can effectively prevent hand slippage and ensure that the worker always maintains a stable grip during operation. This setting not only improves work efficiency, but also reduces the risk of safety accidents caused by hand slippage. In the overall structure of the device, the gripping rod 5 and the connecting rod 4 are integrally formed with the force application rod 1. This setting enhances the integrity and stability of the device. At the same time, the connecting rod 4 and the hooking rod 2 are also integrally formed, which further improves the firmness of the structure. The support rod 3 is fixed to the force application rod 1 by vertical welding to ensure that it will not loosen or fall off during use.

[0020] In an embodiment of the utility model, in order to reduce the manufacturing cost and reduce the waste of resources, the force rod 1, the gripping rod 5, the supporting rod 3, the hooking rod 2 and the connecting rod 4 can all be made of steel bars. These steel bars not only have sufficient strength and toughness, but can also withstand a large applied force. It is worth mentioning that these steel bars can be reused from abandoned steel bars on the construction site, which not only saves costs but also realizes the recycling of resources.
